Hi All,
it has to create
sashelp
aa
dd
ss
dd data sets but macro is not resolving.
Thanks,
S
data test;
infile cards;
input a$;
cards;
sashelp
aa
dd
ss
dd
;
run;
proc sql noprint;
select count(*) into :numb
from test;
;
quit;
%macro a;
%do i=1 %to &numb.;
data _null_;
set test (firstobs=&i obs=&i);
call symput("a&&i",trim(left(a)));
run;
data work.&a&i._01;
set sashelp.class;
run;
%end;
%mend;
%a;
This line is wrong:
data work.&a&i._01;
It should be:
data work.&&a&i.._01;
This piece won't cause an error, but is mildly misleading:
call symput("a&&i", trim(left(a)));
It should become:
call symputx("a&i", a);
Only one ampersand is needed, and switching to SYMPUTX removes all leading and trailing blanks.

You have too many & in your code.
Replace the lines you typed with these
call symputx("a&i",a);
and
data work.a&i._01;
Hint: debugging these things is much easier if your code begins with
options mprint;
